| Research Abstract |
Purposes of this study are synthesis of high purity hBN crystals and realization for their new functions. Band gap of hBN crystal and effect of carbon impurity on intense band edge far-ultraviolet emission of hBN were experimentally clarified. For applications as substrates for graphene, function of hBN graphene layered structure as well as hBN MoS2 structures were investigated on the basis with international collaborations. Fundamental research to understand doping mechanism of large size mismatch system were carried out in the system of Ce doped cBN and AlN.
